Prediction of heat-affected zone using Grey theory

Journal of Materials Processing Technology, 2002
Abstract The amount of deformation and the residual stress, which influence welded plates, are related directly to three aspects of the welding process: the method of heat input; the welding speed and the geometrical conditions; limitations of the weldment.

Prediction of hardness distribution in steel heat affected zone

Science and Technology of Welding and Joining, 1999
A practical method to predict the heat affected zone (HAZ) hardness distribution was studied by considering the effects of prior austenite grain size and tempering on hardenability. For conventionally rolled and thermomechanically processed steels (400–490 MPa grade steels), the hardness distribution between the fusion and Ac3 lines can be fairly well

Microfissuring of Alloy 718 in the Weld Heat-Affected Zone

JOM, 1988
Alloy 718 suffers from microfissuring in the weld heat-affected zone, and compositional, structural and mechanistic causes of this defect have been examined. Both bulk sulfur and bulk carbon increase microfissuring, and heat treatments typical ofhomogenization, solution annealing and age hardening reveal that microfissuring is sensitive to the ...

PWSCC Susceptibility in Heat Affected Zones of Alloy 600

2011
The recent field experience and several experimental results have shown the possible deleterious effect of a heat affected zone (HAZ) induced by welding on the susceptibility to the stress corrosion cracking (SCC) of Alloy 600 of bottom penetrations exposed to primary water of PWRs.
